IMPROVEMENT IN STOVE-PLATES.

TO ALL WHOM IT MAY CONCERN:

' shields or guards, the further object of which is to add to the symmetry ofthe stove.

Beit known that we, DAvIDSTUAnT and ALEXANDER WEMYSS, of Philadelphia, Pennsylvania, have invented an Improved Guard-Plate for Stoves; and we do hereby'declare the following to be a full, clear, and exact description of the same. y f I i Our invention relatesto improvements in the perforated plates which are commonly placed in front of or surround .theire-pots ofstoves, and -our improvements, fully described hereafter, are-such, thatl the plates will `more eifectually conceal the surface of the pot than ordinary plates, and willst the same time direct thc radial:

beat downwards towards the iioQr.

In order to enableothers skilled in the ai't to make and apply our invention, we,.will now proceed to describe themode of constructing and using the Same, reference `being had to the accompanying drawing, which forms apart of this specification, and in whichi 4Figurefl is a face vi'ew of a portion of our improved guard-plate for stoves.

Figure 2, a vertical section `on the line 1-2,.fig. 1, and i Figure 3 a sectional plan onA the line 3-4, iig. 1. Y

.Similar letters refer' to similar parts throughout the several views.

VIt has been usual to surround the cast-iron pots-of stoves, with u. View of'partially concealing the same,

andat the same time permitting the free escape of the radial heat, with a tracery of cast-iron' or openwork'- As heretofore constructed, these guards-failed to conceal the {ire-pot t'o the extent desirable, for while the openspaces permitted the escape ofthe radial heet, they exposed to view the dingy surface of the pot.

Our improved guard-plate consists of. a series of projections,vA, united 'by ariydesired ornamental tracery, and so arranged as to leave open spaces, B. In the present instance, the `projections A consist of sections of hollow spheres, and may be termed dellecting shiel'ds,'as they serve-,to directgtheradial heat downwards, in the course pointed out bythe arrows, 1, through the openings B. -'.llIe shields thus'possess the advantage of directing thc heat to the floor where it is mostjavailable for its proper dissemination throughout the apartment containing the stove. 'd Y The dellectors possess the further advantage of eif'eotually concealing the fire-pot, which is always at the hase of the stove, and so near the floor that the lines of vision may be represented by the arrows 2 2, 2. While the openings B B, therefore, are visible, arid the guard loses nothingV of its ornamental appearance,vthe surface ofthe re-potbeyond the openings, say on the dot-ted line x, cannot be perceivedi It is not essential'thatthe' deectors should be in the form of sectionslof hollow spheres; they may be of di'erent shapes, provided they project outwards above the openings. The method of uniting the shields, and the general ornamentation of the guard-plate, may also be modified without departing from the main feature of lour invention.

We claim 'as our invention, and desire to secure by Letters Patent- A guard-plate, having'deecting shields and open spaces, arranged substantallyin the manner and for the purpose ser. forth.

In testimony whereof, we have signed our names to this specification inthe presence of two subscribing witnesses.
